Abstract
The morphometric differences among 4 biotypes of the European corn borer, Ostrinia nubilalis (Hübner), were studied on the basis of 5 characters: (1) length of Cu1 of the hind wing, (2) width of scutellum I, (3) length of basisternum II, (4) length of tegula, and (5) length of tibia III. The 4 biotypes were from Minnesota, Iowa, Missouri, and Ohio. The Minnesota biotype is distinctly different from the Missouri biotype, and the Iowa biotype is intermediate. The Ohio biotype is more similar to the Missouri biotype than to the Minnesota and Iowa biotypes. These relations on the basis of morphometry are parallel to those in ecological characteristics, namely, survival and diapause. The results suggest that the biotypes of this insect have evolved beyond the stage of ecological and physiological differentiation.This publication has 0 references indexed in Scilit:
